"Subscribed" what an odd word to use for having a link in your corner bookmarks. Not much of a subscription.

I am skeptical that this is what it refers to.

googles also have registered the .net and this was done two day ago.. so it wont become active for quite some time..

Normally we see a service linked into the registere domain nearly after a year that it has been registered.

Sounds more like a del.icio.us clone for me. They wouldn't need an own domain just for links in the upper left corner of the screen.
